Add DBus support by didier13150 · Pull Request #283 · keepassxreboot/keepassxc

didier13150 · 2017-02-10T15:25:13Z

Description

keepassxc can be basically controlled with others applications: open/close databases or exit.

Motivation and Context

React to desktop event automatically:

open database when log in or unlock screen
close all databases when log out or lock screen
exit application

How Has This Been Tested?

Tested on Debug and RelWithDebInfo build type

No DBus interface when compilation option is not set
DBus interface is present when compilation option is set, and then run following commands on a shell
qdbus org.keepassxc.MainWindow /keepassxc org.keepassxc.MainWindow.openDatabase mydb mypasswd mykeyfile
qdbus org.keepassxc.MainWindow /keepassxc org.keepassxc.MainWindow.closeAllDatabases
qdbus org.keepassxc.MainWindow /keepassxc org.keepassxc.MainWindow.appExit

Thanks for your pull request. I think this is mostly implemented by #135, though, which also adds automatic lock support on Windows and OS X, not only Linux.
Maybe you could merge these two PRs and take the best parts from both?

phoerious · 2017-02-25T00:35:08Z

Any further comments on this?

didier13150 · 2017-02-27T15:51:44Z

After a lot of check , #135 seems to subscribe and react to a d-bus event (passive mode). My PR provide another dbus interface (active mode). Both are not mutually exclusive and can be merged together. So I can modify my PR to use #135 lock feature, but it's very hard to do it until #135 is merged or not.

phoerious · 2017-02-27T17:49:34Z

Okay, we'll merge #135 first then and then proceed with your PR. But #135 still needs some work.

Postponing to 2.3

droidmonkey · 2017-05-18T01:55:26Z

I recommend closing this PR and performing a smart cherry pick of the differing capability than what was introduced with #545

TheZ3ro · 2017-05-18T08:29:44Z

@droidmonkey note that #545 is a dbus client (that listens for org.freedesktop.* signals) this instead is a server interface (that expose methods for interacting with KeePassXC via dbus)

Keisial · 2017-05-19T01:25:04Z

I don't think these will be a problem, but if others are added (eg. for reasing an entry), there should be a preferences option to not allow it.

droidmonkey · 2017-05-19T03:00:37Z

Hmmmm. Could this pose a security risk?

didier13150 · 2017-05-19T06:36:37Z

Clearly yes, but outside the scope of keepassxc because you must provide a password on cli to open a database. The risk is that the password of the database can be found on bash_history. This problem is the same than all other cli tools and can be secured by using an askpass program like ksshaskpass or just not using this feature.

mauron85 · 2017-06-22T07:48:06Z

This can serve as base for another projects. Like PR #608 which has potential to replace KeePassHTTP with 'Native Messaging'. In second variant it's using proxy that sits between browser and KeePassXC. Communication is done via UDP packets, but I can imagine to replace UDP for DBUS (on Linux), which would be awesome.

cornfeedhobo · 2017-10-02T20:58:53Z

Looks like this PR is getting lost with time, so I just want to pile on and say I would LOVE to have integration with org.freedesktop.* signals and hook into the Secret Service API, triggering desktop and application actions.

phoerious · 2018-01-14T00:09:04Z

Is this PR getting some love any time soon? If not, I'll close it.

TheZ3ro · 2018-01-14T00:58:07Z

I will look into it ;)

TheZ3ro · 2018-01-15T23:53:45Z

I've rebased this, added a method for locking all DBs (fix #687) and wrote the documentation on the wiki: Using-DBus-with-KeePassXC

Ready for review and merge

src/gui/MainWindow.cpp

    m_ui->setupUi(this);
+
+    #ifdef WITH_XC_DBUS
+    #if defined(Q_OS_UNIX)


This probably will trigger some problem on Q_OS_MACOS.
@weslly can you test this PR on a mac? Thanks

@weslly Ok thanks, I will fix this.

@TheZ3ro Appending && !defined(Q_OS_MAC) on this line seems to solve the compilation issue, but that would mean the #undef macro you used earlier had no effect

@TheZ3ro maybe adding this on src/CMakeLists.txt would be better:

if(APPLE OR MINGW) set(WITH_XC_DBUS OFF) endif()

@weslly pushed a different fix. Now should always work

@TheZ3ro works fine now :)

TheZ3ro · 2018-01-23T20:08:32Z

@weslly when you are free can you test this again? Thanks :)

weslly · 2018-01-23T20:54:43Z

@TheZ3ro got this now:

  set(WITH_XC_NETWORKING ON CACHE BOOL "Include networking code (e.g. for downlading website icons)." FORCE)
 endif()

+if((NOT UNIX) OR APPLE AND WITH_XC_DBUS)


Remove redundant parentheses, use them around the whole OR expression instead.

"Control KeePassXC via DBus"

But TBH, I don't think we need this flag. No matter what's selected here, DBus will always be compiled in on Linux, because we need it for detecting screen locking and for the stupid Unity menu bug workaround.

+    QDBusConnection dbus = QDBusConnection::sessionBus();
+    dbus.registerObject("/keepassxc", this);

This should be org.keepassxc.KeePassXC.MainWindow.

Seems redundant to me using the name 2 times

That's how the standard works.

File should have the usual header, maybe with additional notices.

Sincerely, I would feel silly for adding a copyright notice to an autogenerated file

Shouldn't this file be generated by the build system then (add_custom_target or some shit)?

If we can execute external programs in cmake I would say yes.

qdbusxml2cpp comes in qtbase5-dev-tools package on debian, so it's another dependency to add on linux.

Probably this file won't be edited for a long time, we should leave this here and don't bother too much, we just need to remember that's autogenerated and the header will come in handy
